Ok

Small note the const refers to booster::function not to http::context

And yes because it is more consitent

In C and C++ you read definitions from right to left and from inside out

   int const *p[10]

array of size 10 of pointers to constant int.

Now lets see three different definitions

1. const int **p;
2. int const **p;
3. int * const *p;
4. int ** const p
5. int const * const * const p;
6. const int * const * const p;

Note that 1==2 and 5==6

But when you read for example 2, 3 and 4

4 - constant pointer to pointer to (mutable) int
3 - pointer to constant pointer to (mutable) int
2 - pointer to pointer to constant it.

This makes the position of const much more consistent and easy
to read especially for stuff like

  const int * const &p;

Is harder to understand visually then

  int const * const &p;
